The main problem here is that everything everyone talks about here is lost in translation. Not just from English to Japanese and back, though that is part of it, but more because the questions that get asked are not what people are actually getting at.

I don't think there are very many Summoner players out there at all who care about Physick - in fact I think a lot would agree that we want to be good damage dealers and not healers or jacks of all trades like Red Mage. Unfortunately, because we share some utility with them, and they're two of only three magical damage jobs, of course Physick and Vercure come up in the discussion of the larger issues of SMN being competitive with RDM and other jobs. More unofortunately, the only question that seems to have been taken from that and over to being asked in the Live Letter is "can Physick use INT like Vercure does?" Something that doesn't solve the problem, hardly anyone wants, and of course Yoshida doesn't agree with because Summoner isn't about curing people.

It doesn't look like there's some big consipiracy or lack of care for the job, it's just that the concerns raised by people here are not being conveyed properly to the development team or to the man in charge.
